In this paper we present an efficient numerical method for locating material interfaces in multi-fluid simulations. Starting from a detailed investigation of the moment-of-fluid reconstruction problem, we develop an efficient procedure for the interface reconstruction, based on pre-computing certain values and mapping the domain of the function describing the interface reconstruction onto these values. The interface tracking method is tested on a range of commonly-seen interface advection test problems, where it is shown to increase the computational efficiency of the moment-of-fluid method by a factor of three, with a negligible change in the accuracy of the method.

一种高效的流体矩界面跟踪方法

在本文中，我们提出了一种在多流体模拟中定位材料界面的有效数值方法。从对流体矩重建问题的详细研究开始，我们在预先计算某些值并将描述接口重建的函数域映射到这些值的基础上，开发了一种有效的接口重建程序。在一系列常见的界面平流测试问题上对界面跟踪方法进行了测试，结果表明该方法将流体矩方法的计算效率提高了三倍，而在精度方面的变化可忽略不计。方法。
